WATER-RADIATOR FOR; AUTOMOBILES.

Appiicsiion inea Jamey a, 1901. seria No. 351,558. i

To all whom it may concern:

Be it known that I, CiianLEs F. Seilen., of Buffalo, in the county of Erie and State of New York, have invented certain new and useful improvements in Water-Radiators foi'l Automobiles, of which the following is a specification.

)ly invention relates to water-radiators, such as are used in conjunction with watercooled motors in automobiles.

The objects of my invention are, to increase the water 'capacity of the radiator and provide storage capacity for water so .that the frequentrefilling of the radiator will not be necessary, to provide new and improved air-tubes; and to otherwise improve on water radiators of this type now in use. l

l`o these ends the invention consists in the construction, arrangement and combination of parts to be hereinafter described and particularly pointed out in the appended claims.

ln the drawings in which similar numerals of reference' refer to similar parts:-Figure 1 is a front elevation of a radiator embodying my improvements. Fig. 2 is a horizontal section taken on line 2 2, Fig. 1. Fig. 3 is a central vertical longitudinal section through the radiator. Fig. 4 is a horizontal section taken on line 4--4, lFig. 3. Fig. 5 is a vertical section taken on line 5'5, Fi". 3. Figs. 6 and 7 are perspective views of a sheet of metal, preferably thin sheet copper, showing the manner of preparing the saine to form the air tubes for the radiator. Fig.

.S is a perspective view of one of the air-tubes.

Fig. S) is a detached inverted perspective view of one of the bolt-blocks wit-hin the out-let chamber. Fig. 10 is a vertical longitudinal section of a radiator embodying my invention in modified form' v The reference n uineral l() designates the radiatorv casing which may be of any design and comprises a fop wall 11, a bottoni wall 12, end walls 13, a front wall 14 having a large central opening, and a rear wall 15 also provided with a large central o -ening corresponding in size and outline wit the opening in said front wall.

. Arranged 'arallel with'the end weils and connecting tie front and rear walls of the easing at the ends of the openings therein mare transverse interior walls 16 which extend vertically from the top to the bottoni of said Specification of Letters Patent. i

\ openings, forming water-spaces' 17 and having their upper ends inclosed .by horizontal walls 1S; said waterspaces servirifr as stor-A age-chambers. Located within tie .space formed by said openings are numerous airtubes'lt) arranged in horizontal rows and having the tubes in staggered relation from top to bottom. These tubes are provided with enlarged ends or collars .Z() which lic in contact to provide intervening spaces 2l', between the tubes of adjacent rows and between the tubes of each row, which spaces form narrow staggered water passages. This arrangement, however, is not new, Lbut the particular formation oi the tubes herein shown is a very important feature of my invention. Each of the airtubes 19 1s formed of a sheet of thin copper having opposite marginal portions folded, as at 22, and then bent or curved ata right-angle to the folded ends to form a. tube of the desired cross-sectional shape; the shape preferred being rectangular and preferably sfilare, but if desired` the tubes majr be eylini ical,

octagonal, or of any other formation in crossl section.

1n forming the tubes. the folded portions thereof are on the exterior and form integral exterior collais, vand when assembling the same to foi-in the radiator, the collars of adjacent tubes are in Contact and united; thus forming the water passages between the tubes. The latter are preferably soldered together at their-enlarged ends and the collars thereof serve to close theends of said passages. The width of the water-passages is governed entirely bv the number of times the sheet copper is folded ato )positie ends; but I have found that a double fold as shown in Figs. 6 and 7, on the gage of sheet copper usually employed `for radiators of this ty e, answers the purpose admirably for t e greater portion of automobiles now in use; but in some cases a single fold, causing a reduction in the width of the water-passages,

or merc than two folds, causing-an enlargement of the water-passages, will be found more effective.

The air-tubes completelv fill the openings A .i

letfehaniber :23 at the top of the casing, and

the upper wall of the outletchainber 24 at the bottoni of the casing. Frein this it will be understood that waterfchainbers are provided above, below, and at the lsides of the assembled ar-tubes.

As one of the important features of my in- 5 vention is to increase the capacity for holding water7 I provide for enlarging the outletchamber 24, by placing the bar-heads or blocks 25 of the sccurinv-bolts 26 within said chamber, instead of plzacing them beneath 10 the bottom 12 of the casing, as has heretofore been practiced.- This ermits me to use as a part of the outlet Yc amber, considerable s ace which has heretofore been wasted; yt .ereby increasing the capacity for the cooling water without enlarging the radiator. As shown in Figs. 5 and 9, the bar heads or blocks 25 are provided on theiriunder-sides with grooves 27 to permit the free circulation' of water;` said heads or blocks being of suiiicient width to provide a good bearing 'and of a length to extend fully across the chamber with the ends thereof in contact with th front and rear walls of the casing. The Shanks extend through openings in the bottoni and are adapted to be passed through \the frame of the automobile; nuts being a plied to the ends of the Shanks to secure y allix the radiator to the frame.

For a morel secure connection between the 30 front wall of the casing and the interior walls 16, also between said front wall and the assembled tubes at the top and bottom, I provide angleirons 2S, each of which has one web thereof soldered and riveted t`o said front wall and its other web soldered to the interior walls 16, or to the tubes, as the case may be, and as clearlyshown in Fig; 3. This makes a more perfect water-tight seam than has heretofore been resided at this point.

Within the in etchan1ber I arrange water inlet-pi 'es 29 having their lower or outlet ends soidercd into openings in the walls 1S and their upper or inlet ends terminating a considerable distance above the air tubes forming the bottom of the inlet-chamber. As is common in radiators'of this type, a illihg-opening 30 is provided throng i which water is poured into the radiator. The latter has connection with the water-jacket o the motor by suitable pipes connected to the inlet 31 of the inletchamber 23, and the outlet 32 of the outlet chamber 24.

The water enteis the inlet-eliainher and finds its' way through the various water-passages 21l to the outlet, from whence itpasses out to the water jacket of the motor through the outlet 32, and is pumped back into the inlet chamber 23 through the inlet 31 thereof, being in constant circulation and thor- 00' oughly cooled as it passes between the airtubes through which vthe air asses.. Vthen first filling the radiator with t e cooling water, the side,or storage chambers 17 are filled from the bottom when the escape of the water from the outlet chamber is slower than the supply thereto through the water-pas sages 21, and said storage-chambers are also filled from the top when the level of the water in the inlet chamber is even with or above the inlet ends of the inlet pipes 29, through 70 which latter it iows and enters said storage chambers at 33.

When the 'water rises intov the storage chambers 17 from.tlie outlet-chamber and also enters said chambers through the inletpipes '29, provision must be made for the escape of air from said chambers. This '1 preferably do by means of air-escape pipes 34. ocated within theinlet-chainber and o ening at one end into the storage cham eis through the upper walls 18 thereof; said air escape-pipes terminating at their other ends in a plane above the inlet-ends of the water inlet-pipes 29.- If desired, the walls 18 at the upper ends of the side or storage chambers may each have one or more o enings, such as shown at 35, through whic i water may be supplied to said c ambers; these openings being used to more quickly fill the ciambers. 90

The construction above described is the referred embodiment of my invention, and is arranged that the water when Afirst supplied to t-he radiator, must pass down bctween the air-tubes until the inlet-chamber is almost filled, after which it may also pass into the side storagc-chamb:is` through the inlet-pipes 29. When the small pcrforations 35 are formed in thcwalls 1S at the upper ends of said storage-chambers, the ilow of 10g water therethrough is much less than will pass through the water-passages 21, and therefore it will be permitted to rise to a )oint where it will overi'low through the inet-pipes`29; particularly as it is poured into 105 the radiator much quicker than it can flow through the passa es 21.

Another embodiment of my invention is shown in Fig. 10, in which the upper ends of the side storagechambers are open and the 11( interior wallsl, extended upward .and inward into the inletchamber, as at 36. Whenl so constructed the water will enter the side chambers from the bottom, and will also flow over the to )s of the walls 16. l 11:
